Namibian discoveries alter high-impact well activity

Namibian discoveries alter high-impact well activity

While historically natural gas discoveries have vastly outnumbered liquids volumes, a reversal is expected in these results this year mainly due to two significant oil offshore discoveries in Namibia. 

These are the offshore TotalEnergies’ Venus and Shell’s Graff discoveries in the Orange Basin. 

This is expected to result in drilling of high-impact oil and gas prospects that is set to rebound this year after a disappointing 2021, when success rates plunged toward record lows, according to a Rystad Energy report.Online publication, Offshore, reported that bucking recent global trends, discovered liquid hydrocarbons have accounted for 1.2 Billions of Barrels of Oil Equivalent (Bboe) or almost 70% of the volumes this year, while gas discoveries total about 550 (Million barrels of oil equivalent) Mboe. 

More than 45% of wells completed so far in 2022 are in South America and Africa, followed by Australia and Europe with 16% each of completed wells. By individual country, Australia accounted for the most completed high-impact wells with three, followed by Guyana and Namibia with two wells each.

The Rystad report shows these critical wells have found hydrocarbons 47% of the time so far this year, up from a measly 28% for 2021. With about four months still to go in 2022, discovered volumes from high-impact wells have nearly quadrupled to more than 1.7 Bboe, which has been described as a positive sign for global hydrocarbon supply.

“A total of 33 high-impact wells are set to be drilled this year, the largest annual number since Rystad started tracking the sector in 2015. This is only slightly more than last year’s 29 high-impact probes, which only yielded 450 Mboe because of the low success rate,” Offshore reported. 

The Rystad report classifies high-impact wells through a combination of factors, including the size of the prospect, whether they would unlock new hydrocarbon resources in frontier areas or emerging basins, and their significance to the operator.

“Last year was disappointing for discovering gas and liquid volumes from high-impact wells, but 2022 is on track to make up for that slump. If the success rate seen in the first half of 2022 holds for the full year, we could be in for one of the most productive annual volumes total on record,” said Rystad Energy senior analyst Taiyab Zain Shariff.

Of the 33 expected high-impact wells in 2022, 19 have already been completed, four are in progress and 10 are scheduled to be completed before next year. More than half of the wells drilled so far in 2022 are considered a “focus for the company,” indicating that more operators are narrowing their geographical range of exploration and focusing on core regions instead of frontier areas.

The global oil majors and other exploration and prospecting companies account for more than 60% of the high-impact wells completed this year. Majors have drilled eight high-impact wells, of which four resulted in commercial discoveries: TotalEnergies’ Venus and Shell’s Graff oil discoveries in Namibia, Exxon Mobil’s Fangtooth oil find in Guyana and Eni’s XG-002 gas discovery in the United Arab Emirates (UAE).

Of the 19 high-impact wells completed this year, 47% resulted in a commercial discovery, with the rest either dry or uncommercial and one still awaiting results. Only one find was a pure oil discovery, while the rest were either gas or liquids with associated gas. This year’s success rate is almost equivalent to 2020, which was one of the most successful years in volumes from high-impact wells, Rystad said.

Rystad expects 14 high-impact wells to be completed or spudded for the rest of 2022, six of them by majors.

The rest of the wells planned for this year are distributed throughout Africa and the Americas, with some wildcats to watch in Southeast Asia as well. Most of these are classified “focus for the company,” followed by wells in frontier basins.

Offshore emphasized that the frontier wildcats will be interesting to watch as they may open entirely new petroleum regions. Rystad noited that these include Kuwait’s first offshore probe in 32 years, where Halliburton has a contract to drill six exploration wells for state-owned Kuwait Petroleum Corp. If successful, this campaign could help restart Kuwait’s offshore legacy fields after a long hiatus.
